Patented Feb. 20, 1940 SHOE JACK Euclid I. La. Chapelle, Brockton, Mass.Application June 28, 1939, SerialNo. 281,573 3 Claims. (01. 12 12'1),

Myinvention relates to shoe jacksand more particularly to the typeadapted to support a shoe, while on its last, by a toe-rest member,adapted to engage and support the forepart of the shoe and by a movablelast-pin member, adapted to support the heelpart of the shoe and whichis provided with a strong spring urging the last-pin member and the shoedownwardly and towards the toe-rest member to thereby ,firmly hold theshoe on the jack.

To accommodate shoes of various sizes, a shoe jack of this type isprovided with a toe-rest member movable towards and from the last-pinmemberland having adjusting means whereby it may be held in set positionrelatively to the last pin member. Thus several preparatory adjustmentsare necessaryjin jacking any ordinary case of shoes in the general runof a shoe factory.

With this type of jack, once the shoe has been placed on the last-pinmember, the forepart of theshoe then is set upon the toe-restmember andin thus setting the forepart of the shoe, the toe-end of the shoe mustbe engaged and. lifted up by the operators left hand so as to move the25 movable last-pin member away from thetoe-rest member against thetension of the aforesaid becomes enormous and, notably so, when it isconsidered that all of this laborious work is being performed. by theoperators left hand.

35 It is the main objective of my invention to provide a shoe jack ofthis general character, but so built and arranged that shoes of varioussizes may be readily accommodated without need of any adjusting meansand so built and ar- 40tranged that shoes may be set on and removed fromthe jack more rapidly andwith far less effort than heretofore possibleand, even sowhen the tension of the aforesaid strong spring urgingthe'last-pin towards the toe-rest member is 45,:much, stronger than theusual tension ofthe spring on the ordinary jack.

l i As further shown in the drawings: i

My novel shoe jack comprises a'floor base column I, which supportstheadjustable portion 2 of the column. The said floor base column having atits lowerend, the external screwthread 3 which is threaded into theinternal upper end of the floor base column I and is locked in setposition when the desired height of the head of the jack has beendetermined by the locking means 4 having the convenient handle 5. Theupper adiustablecolumn 2 is provided'with the slots 6 and the clampingcollar 1 which is clamped by the screw 8 and held in clamped conditionby the lock 9. The said screw 8, being conveniently operated by thehandle I 0.

The head supporting member I I has adownwardly projecting portion I2which rotatably fits IS on which the rocking frame 20 is oscillatinglysupported. Slideways 2|, are provided upon the said rocking frame andextend rearwardly from the pivot [9. The said rocking frame 20 has a.forwardly extended arm 22 which carriesthe pin 23 to which'the upper endof a strongspring24 is secured, its lower end being securedto the pin 25which is provided in the lug 26 which extends upwardly from the headsupporting member II. The brackets 21 and 28 are secured. to the bracketarms l5 and IS; the said bracket 2'! extending OFFICE 7 required.

The said holding block also has the hole 32:

through its entire length and it receives the rod 33 which may be heldin adjusted position by the; set-nuts 34. The shoe forepart supportingmem ber 35 is secured to the upper end of the said adjustable rod 33.Mounted forrfree movement.

towards and from the shoe forepart supporting member 35 in the slideways2| of the"'rocking framezn is the slidingblock'36 which'carries-the lastpin' memberlor, in'ii'a broader sense, the shoe he'elpartsupportingimember '31.

Towards the rear end. of "the slideways 2i I have provided a 'novelmoving :meansadapted; to oscillate the rocking frame 20-andwhichHconsists-of anupright post" 33 which carries the forearmengaging member 38 whereby the rocka ingiframe may beoperated to rockupon the pivot l Q againstthe tension-of the-strong spring 24'.

under the influence :of the pressure applied thereto by theoperator-preparatory to the setting of the shoe' on and to the removalof the shoefrorn the-jack. The length of the rocking frame from 'thepivot I9,:extending*rearwardly,is such that the frame may be easilyrocked against the ten sion of the strong I spring 24 by thecomparatively. small degree of pressure being applied by the operatorupon the forearm" engaging 'member 39. Af-tez th'e'shoe has been placedupon the last pin member 31 and moved; with the saidmember,

towards the shoe forepart supporting member 35 toaccommodate-thesize ofthe shoe relatively to the shoe forepar-t supporting member 35, therocking frame =20, is then rocked and in thus being rocked, the last-pinmember 3'! is moved away from" the shoe forepart supporting member 35and in providing manuallytoperatedmoving means,

the forepart of-the shoe is elevated above the shoe" forepart supportingmember so that the *forepart 'of'the shoe then maybe easily set on or,

removed from the jack. .In this connection, it is to-be'noted that insetting the shoe on and in removing the shoe from the-toe-rest of theordinary shoe'jaclgthere is more or'less frictional contactof-the shoewith the toe-rest and thus liability ,of damage to'a shoe having adelicate upper exists due tothe-ifact that: the operatorshand isunsteady in lifting run-the toe-end of the-shoe against the strong 1spring -,--tension upon the lastpin member; Thisobjectionable conditionalso is {eliminated byithe use -of my improved. shoe jacks p t It is: tobe-further noted that the-operators hands: are free to set the-shoe onor toremove the shoefrom the jack: and of all the laborious worknow-involved in'the performance of these steps in the-use'of theordinary shoe jack. Moreover,

and notably 'a forearm "engagingm'ember, such as herein shown, theoperator then"maylstand on both feet at all times, which would beimpossible were a foot 'treadle provided as a moving means.

My invention is not to be limited to the herein shown construction whichmaybe varied within the scope of the'appended claims, which are to beinterpreted broadly and limited only by the requirements of the priorart. I

Each claim is to be interpreted as specifically stated therein.

Having thus explained the nature of my invention ands'hown the best formof embodiment now to me known, what I claim as new and desire to secureby Letters Patent of the United States is:
